My suggestion to Samsung please add feature to take a screenshot with 2/3 fingers slide down or something more easy as screenshot by gesture feel more complicated

You may try Accessibility>Interaction and Dexterity>Assistant menu feature

or go for one hand operation+(samsung official app)

simply go for assistant menu or download one handed operation from galaxy store. If you want to add screenshot toggle to your quick panel then search a video how to do this in YouTube. you'll find the solution

as of now Enable assistant menu, this is best way ,by this option you can also perform other important task such as screen off, navigation, sound, screen rotation, power off menu, notification panel and also specific app option available

To enable assistant menu just go to

settings>>accessibility >>interaction and dexterity>>assistant menu>>enable and also click on it and enable>> assistant plus menu
